How to move images and video to SD Card?

Question

How to move images and videos from internal storage to SD card in Samsung Galaxy S7?

I saw advice to go to

My Files -> Images (or other) -> Options -> Select -> All 

then move. But I can't accept this advice because it looks like flatten directory structure, which I need not to.

UPDATE

I want to move files which are created by camera.

UPDATE 2

I want BOTH:

1) make camera put NEW images and videos to new location

2) make OLD images be located in new location and be seen by gallery

UPDATE 3

So I expect answer suggest either automatic solution, or fully defined manual solution. For example, if solution requires moving files, it should specify BOTH source AND destination directories.

Answer 1

Yes, your advice flattens the directory structure.

Therefore the only thing you can do is:

1. Go to My Files -> My Device.
2. Navigate to the files/folders you want to move
3. Select the files and folders you want to move
4. Hit More -> Move
5. Select the destination
6. Hit Done
7. Repeat steps 2 - 6 until you are done.

Files from the Camera app are located at DCIM/Camera/

For changing the default location of photos and videos, go to the Camera app's settings and change the default location.
